Want to thrive in a compact corner of the galaxy while competing with sprawling empires? This guide will walk you through how to excel at the tall playstyle in Stellaris, focusing on efficiency, specialization, and smart empire management.

Tall vs. Wide: What’s the Difference?

Tall and wide are two core strategies in Stellaris:

• Tall Empires focus on fewer systems and colonies, keeping empire size low to minimize penalties to research, traditions, edicts, and campaigns.
• Wide Empires aggressively expand across the map, generating more raw output but incurring higher scaling penalties.

Tip: Empire Size is mostly driven by pops, not land. Fewer colonies = fewer pops = lower penalties.

Core Strategies for a Tall Empire

1. Maximize Resource Income Through Vassals

Vassals are your solution to resource shortages:

• Create Vassals through war or diplomacy.
• Extract Resources by customizing their agreements—demand energy, minerals, alloys, and research.
• Keep Them Loyal with perks like Shared Destiny, good relations, or military pressure.

2. Federations: Collective Power, Minimal Growth

Use federations to multiply your power without increasing empire size:

• Choose a federation type that complements your playstyle (e.g., Research Cooperative or Trade League).
• Share fleets and tech while influencing federation laws to suit your needs.

3. Edicts and Leaders: Efficiency Without Bloat

With a small empire, you can focus more on quality than quantity:

• Leaders: Prioritize those with powerful economic or scientific traits.
• Edicts: Activate ones like Mining Subsidies, Capacity Subsidies, or Production Targets—more value per pop.

4. Planetary Specialization and Ascension

Every world must perform at peak efficiency:

• Planet Specialization: Designate worlds for research, energy, alloys, or unity.
• Planetary Ascension: Use Unity to boost output and reduce empire size impact.
• World Types:
  • Ecumenopolis: Ideal for alloys and consumer goods.
  • Machine World or Hive World: Perfect for synthetic or hive empires.
  • Habitats & Ring Worlds: Expand vertically without bloating your empire.

5. Stability and Happiness = Efficiency

Maxed-out stability boosts all resource output:

• Raise pop happiness with high living standards and amenities.
• Build Deep Space Black Sites to boost stability via starbases.
• Align factions with government ethics for extra approval bonuses.

6. Branch Offices: The MegaCorp Advantage

Playing a MegaCorp? Use branch offices to grow tall off-world:

• Establish Branch Offices in other empires for free income and strategic buildings.
• Gain value from other nations’ pops without bloating your empire size.

Why Go Tall?

• Lower Empire Size Penalties = faster research and traditions.
• Highly Specialized Worlds = huge returns per colony.
• Fewer Admin Burdens = less micromanagement and stronger unity economy.

Handling the Endgame as a Tall Empire

You may be small, but you’ll be mighty:

• Build a powerful navy using Alloy Worlds and Strategic Coordination Centers.
• Use Mega Art Installations, Dyson Spheres, and Ring Worlds to sustain peak output.
• Defend chokepoints with citadel starbases and FTL inhibitors.
